TECHNICAL FIELD

The present invention relates to spiroimidazolone derivatives and use thereof.

BACKGROUND ART

Parathyroid hormone (PTH) is a major regulator of calcium homeostasis and its main target organs are considered to be the bones and kidneys. Native human parathyroid hormone is a polypeptide consisting of 84 amino acids. This hormone is secreted from the parathyroid gland in response to low blood calcium levels, and acts on osteoblasts (bone-building cells) in the bones and tubular epithelial cells in the kidneys. This hormone interacts with a cell surface receptor molecule called PTH-1 receptor or PTH/PTHrP receptor, which is expressed by both osteoblasts and renal tubular cells.

PTHrP (PTH-related protein), the major cause of humoral hypercalcemia of malignancy (HHM), also has normal functions including developmental roles. PTHrP has 141 amino acids, although mutants also occur that result from alternative gene splicing mechanisms. PTHrP plays a key role in the formation of the skeleton through a process that also involves binding to the PTH-1 receptor (Non Patent Literature 1, Non Patent Literature 2).

Regulation of calcium concentrations is necessary for normal functions of the gastrointestinal system, skeletal system, nervous system, neuromuscular system and cardiovascular system. Synthesis and release of PTH are primarily controlled by the serum calcium level. Synthesis and release of PTH are stimulated at low serum calcium levels, and synthesis and release of PTH are suppressed at high serum calcium levels. PTH, in turn, maintains the serum calcium level by directly or indirectly promoting calcium entry into the blood at three calcium exchange sites: intestine, bone and kidney. PTH contributes to net gastrointestinal absorption of calcium by assisting in the renal synthesis of active vitamin D. PTH promotes calcium mobilization from the bone to serum by stimulating differentiation of osteoclasts that are bone-resorbing cells. This also mediates at least three main effects in the kidney (stimulation of tubular calcium resorption; enhancement of phosphate clearance; and promotion of an increase in the enzyme that completes the synthesis of active vitamin D). PTH is considered to exert these effects primarily through receptor-mediated activation of adenylate cyclase and/or phospholipase C.

Disruption of calcium homeostasis may produce many clinical disorders (e.g., serious bone disease, anemia, renal dysfunction, ulcers, myopathy and neuropathy), and this usually results from conditions that produce an alteration in the level of parathyroid hormone. Hypercalcemia is a condition characterized by an elevated serum calcium level. This is often associated with primary hyperparathyroidism in which excessive PTH production occurs as a result of parathyroid gland lesions (e.g., adenoma, hyperplasia or carcinoma). Humoral hypercalcemia of malignancy (HHM), another type of hypercalcemia, is the most common paraneoplastic syndrome. This appears to result in most instances from the production of a certain protein hormone that shares amino acid homology with PTH by tumors (e.g., squamous cell carcinoma, renal carcinoma, ovarian carcinoma or bladder carcinoma). These PTHrPs appear to mimic the effects of PTH on the kidney and skeleton in some degree, and are considered to interact with the PTH receptor in these tissues. PTHrP is usually found at low levels in many tissues including keratinocytes, brain, pituitary gland, parathyroid gland, adrenal cortex, medulla, fetal liver, osteoblast-like cells and lactating mammary tissues. For many HHM malignant tumors, high levels of PTHrP are observed in the circulatory system, and this leads to elevated calcium levels associated with HHM.

The pharmacological profiles of PTH and PTHrP are nearly identical in most in vitro assay systems, and elevated blood levels of PTH (i.e., primary hyperparathyroidism) or PTHrP (i.e., HHM) have comparable effects on inorganic ion homeostasis (Non Patent Literature 3, Non Patent Literature 4). The similarities in the biological activities of the two ligands can be explained by their interaction with the PTH/PTHrP receptor, a common receptor expressed abundantly in the bones and kidneys (Non Patent Literature 5).

The PTH-1 receptor is homologous in primary structure to some other receptors binding to peptide hormones, such as secretin (Non Patent Literature 6), calcitonin (Non Patent Literature 7) and glucagon (Non Patent Literature 8); these receptors together form a distinct family called receptor family B (Non Patent Literature 9). Within this family, the PTH-1 receptor is unique in that it binds to two peptide ligands and thereby regulates two separate biological processes. A recently identified PTH receptor subtype called PTH-2 receptor binds to PTH but not to PTHrP (Non Patent Literature 10). This finding has implied that the structural differences in the PTH and PTHrP ligands determine the selectivity for interaction with the PTH-2 receptor. The PTH-2 receptor has been detected by RNA methods in the brain, pancreas and vasculature; however, its biological functions have not been determined (Non Patent Literature 10). The family B receptors are assumed to use a common molecular mechanism for engagement with their own cognate peptide hormone (Non Patent Literature 11).

The PTH-1 receptor binds to both PTH and PTHrP and causes not only intracellular cAMP accumulation and adenyl cyclase (AC) activation but also signal transduction to phospholipase C (PLC), thereby leading to the production of inositol trisphosphate (IP3), diacylglycerol (DAG) and intracellular calcium (iCa²⁺) (Non Patent Literature 12, Non Patent Literature 13).

Osteoporosis is a potentially crippling bone disease and is observed in a substantial portion of the elderly population, in pregnant women and even in juveniles. The term “osteoporosis” refers to a group of disorders consisting of different constituents. Osteoporosis is clinically classified into type I and type II. Type I osteoporosis occurs primarily in middle-aged women and is associated with menopausal estrogen loss, while type II osteoporosis is associated with the elderly. Patients with osteoporosis are considered to benefit from novel therapies designed to promote fracture repair, or therapies designed to prevent or reduce fractures associated with the disease.

This disease is characterized by reduced bone mass, decreased bone mineral density (BMD), decreased bone strength and an increased risk of fracture. Currently, there is no effective cure for osteoporosis, although estrogen, calcitonin, and etidronate and alendronate that are bisphosphonates are used to treat the disease with various levels of success. These agents act to decrease bone resorption.

PTH(1-34) (teriparatide) has a strong bone anabolic effect and induces significant increases in bone mineral density and bone strength. Subcutaneous administration of human PTH(1-34) increased the spine bone mineral density (BMD) by 8% in one year and decreased the risks of vertebral fracture and nonvertebral fracture by 65% and 55% in two years, respectively (Non Patent Literature 14). Subcutaneous administration of human PTH(1-84) also increased the spine bone mineral density (BMD) by 6.9% in 18 months and decreased the risk of vertebral fracture by 58% (Non Patent Literature 15). Parathyroid hormone is currently believed to be one of the most effective treatments for osteoporosis (Non Patent Literature 16). Importantly, hPTH(1-34) must be administered in a pulsed manner (e.g., subcutaneous injection once daily) to achieve its bone-forming effect. Longer administration of PTH(1-34) such as by use of a continuous infusion pump mechanism activates bone-resorptive responses mediated by osteoclasts much stronger than bone-forming responses mediated by osteoblasts, and thus PTH(1-34) exerts a net degradation effect on the bone.

Although parathyroid hormone is believed to be one of the most effective treatments for osteoporosis, only less than 1% of patients with osteoporosis use teriparatide and the average duration of teriparatide is 12 months (Non Patent Literature 16). Teriparatide must be administered by self-injection. The fact that it is difficult to use a pen-type device for self-administration is the principal cause of the low compliance of teriparatide-administered patients. It is obvious that noninvasively, preferably orally, available compounds having a PTH-like effect with clinical efficacy in osteoporosis similar to that of parathyroid hormone can considerably improve the compliance of patients with regard to the administration, and that the compounds can be the most useful therapeutic option for patients with osteoporosis.

There are many low molecular weight agonists for the GPCR family A; however, only a limited number of low molecular weight ligands for the GPCR family B have been reported (Non Patent Literature 17). Low molecular weight agonists have been reported for the GLP-1 receptor, calcitonin receptor and PTH1 receptor belonging to the GPCR family B; however, there is no compound used in clinical applications for the treatment of diseases.

Thus, the compounds of the present invention may have an asymmetric carbon atom in the molecule and may be present as optically active forms and racemates, but the present invention is not limited to either of them and includes both of them.

The present invention includes all isotopes of the compounds represented by the formula (1) or (2). In the isotopes of the compounds of the present invention, at least one atom is replaced by an atom having the same atomic number (proton number) but having a different mass number (sum of the number of protons and the number of neutrons). Examples of the isotopes contained in the compounds of the present invention include a hydrogen atom, a carbon atom, a nitrogen atom, an oxygen atom, a phosphorus atom, a sulfur atom, a fluorine atom and a chlorine atom, including 2H, 3H, 13C, 14C, 15N, 17O, 18O, 31P, 32P, 35S, 18F and 36Cl, respectively. In particular, radioisotopes that decay by emitting radioactivity such as 3H and 14C are useful in body tissue distribution tests for pharmaceuticals or compounds. Stable isotopes do not decay, are almost equal in abundance and do not emit radioactivity, and thus they can be used safely. The isotopes of the compounds of the present invention can be converted according to conventional methods by substituting a reagent containing a corresponding isotope for a reagent used for synthesis.

The compounds according to the present invention may exhibit crystalline polymorphism, but are not particularly limited to any one of these, but may be in any one of these crystal forms or exist as a mixture of two or more crystal forms.

The compounds according to the present invention include prodrugs thereof. The prodrugs are derivatives of the compounds of the present invention which have chemically or metabolically decomposable groups and are converted back to the original compounds after administration in vivo to exhibit their original efficacy, including complexes not formed with covalent bonds, and salts.

Step 25 is a method of reacting the amino-amide derivative (35) with a thiocarbonylating reagent such as di(2-pyridyl)thionocarbonate in an appropriate solvent such as tetrahydrofuran. The reaction temperature is 0° C. to room temperature, for example, and the reaction time is 0.5 hour to several hours. The thiohydantoin derivative (33) is isolated by a common technique and, if necessary, may be purified by crystallization or chromatography.

The alkynyl derivative of the general formula (1) wherein W is acetylene and R₁ is optionally substituted aryl or heteroaryl (formula XI) can be synthesized through an acetophenone derivative (formula X).

Step 26 is a method of condensation with an aryl ester (36) in an appropriate solvent such as tetrahydrofuran or diethyl ether in the presence of a base such as lithium hexamethyldisilazide (LHMDS) or lithium diisopropylamide (LDA) preferably with the addition of DMPU. The reaction is performed at −78° C. to room temperature for 1 to 24 hours in an N₂ atmosphere. The resulting acetophenone derivative (formula X) is isolated by a common technique and, if necessary, may be purified by crystallization or chromatography.

Step 27 is a method of synthesizing an alkynyl derivative (formula XI) by subjecting the acetophenone derivative (formula X) to dehydration reaction. Specifically, 1 to 10 equivalents of a dehydrating agent, preferably 2-chloro-1-methyl-pyridinium iodide, and an appropriate base, preferably triethylamine, are added and reacted in an appropriate solvent such as dichloromethane at 0° C. to a temperature under heating. The resulting alkynyl derivative (formula XI) is isolated by a common technique and, if necessary, may be purified by crystallization or chromatography.

The substituted alkylene derivative of the general formula (1) wherein W is branched alkylene or haloalkylene (formula XII) can be synthesized as follows, for example.

The substituted alkylene derivative (formula XII) can be obtained by nucleophilic substitution reaction with a ketal-sulfonamide derivative (37) as a raw material to introduce an alkyl group or a halogen atom onto the carbon adjacent to the sulfonyl group (Step 28), ketal deprotection reaction (Step 20) and the steps shown in Schemes 5 and 6.

Step 28 is a reaction of a ketal-alkylenesulfonamide derivative (37) with an electrophilic reagent such as an alkyl halide or NFSI (N-fluorodibenzenesulfonimide) in an appropriate solvent such as tetrahydrofuran in the presence of a base such as n-butyllithium or lithium diisopropylamide. The reaction temperature is −78° C. to room temperature, for example, and the reaction time is 0.5 hour to several hours. The ketal-sulfonamide derivative (38) is isolated by a common technique and, if necessary, may be purified by crystallization or chromatography. In this reaction, one or two substituents are introduced onto the carbon atom adjacent to the sulfonyl group, and the equivalents of the base are controlled according to need. In the introduction of two substituents, two substituents can be introduced all at once using an excess of a base; however, it is desirable to once obtain a compound having one substituent introduced thereinto by purification and then introduce the other substituent.

The guanidine derivative of the general formula (1) wherein X is a nitrogen atom (formula XIII) can be synthesized through a guanidine intermediate (41).

The guanidine intermediate (41) can be synthesized from a thiohydantoin derivative (39) through an isothiourea derivative (40). The guanidine derivative (formula XIII) can be synthesized from the guanidine intermediate (41) by the reactions of Step 5 and subsequent Step 1, for example.

Step 29 is S-alkylation reaction of a thiohydantoin derivative (39). Specifically, this is a method of reacting a thiohydantoin derivative (39) with an alkyl halide reagent such as methyl iodide in an appropriate solvent such as methanol in the presence of a base such as sodium hydroxide. The reaction temperature is room temperature to the boiling point of the solvent, for example, and the reaction time is several hours to 24 hours. The isothiourea derivative (40) is isolated by a common technique and, if necessary, may be purified by crystallization or chromatography.

Step 30 is a reaction of converting isothiourea to guanidine. Specifically, this is a method of reacting the isothiourea derivative (40) with a substituted primary amine or substituted secondary amine in an appropriate solvent such as dimethylacetamide in the presence of an acid catalyst such as acetic acid. The reaction temperature is room temperature to the boiling point of the solvent, for example, and the reaction time is 0.5 hour to several hours. The guanidine derivative (41) is isolated by a common technique and, if necessary, may be purified by crystallization or chromatography.

The derivative compound represented by the general formula (2), wherein Z includes alkenylene, can be synthesized from a diolefin derivative (formula XIV) by olefin metathesis reaction (Step 31).

Step 31 is a method of cyclizing a diolefin derivative (formula XIV) using a Grubbs reagent in an appropriate solvent such as dichloroethane. The reaction temperature is room temperature to the boiling point of the solvent, for example, and the reaction time is several hours to 24 hours. The macrocyclic derivative (formula (2)) is isolated by a common technique and, if necessary, may be purified by crystallization or chromatography.

The derivative compound represented by the general formula (2), wherein Z includes an amido group, can also be synthesized from a derivative having a primary amine or secondary amine at one end of the compound and a carboxylic acid at the other end (formula XV) by amidation reaction (Step 7).

The compound of the formula (2) is synthesized by cyclizing a derivative having an amine and a carboxylic acid at the ends (formula XV) using the above-described method of Step 7.

The derivative compound represented by the general formula (2), wherein Z includes triazole, can also be synthesized from a derivative (42) having an alkyne at one end of the compound and an azide at the other end using click chemistry (Step 32).

Step 32 is a method of reacting an azide and an alkyne in a derivative (42) having the alkyne and the azide at the ends in an appropriate solvent such as acetonitrile or tetrahydrofuran in the presence of a copper catalyst such as CuI with the addition of a base such as diisopropylethylamine or 2,6-lutidine and ascorbic acid if necessary. The reaction temperature is room temperature to the boiling point of the solvent, for example, and the reaction time is 1 to 24 hours. The derivative represented by the general formula (2) is isolated by a common technique and, if necessary, may be purified by crystallization or chromatography.

Derivatives can be synthesized from compounds obtained in Schemes 21, 22 and 23 by olefin hydrogenation reaction, olefin oxidation reaction, sulfur atom oxidation reaction, deprotection reaction of various protecting groups and the like as necessary.

Compounds containing functional groups such as alkenyl, amine, carboxylic acid, alkynyl and azido functional groups at the ends, the raw materials used in Schemes 21, 22 and 23 and the like for synthesizing the general formula (2), may be synthesized by previously introducing these functional groups into a carboxylic acid derivative (7), a bromide derivative (9), a styrene derivative (11), an aryl halide derivative (21), an aldehyde derivative (24), a substituted phenylboronic acid (34) and the like and subjecting them to the same method as the method of manufacturing the general formula (1), or may be synthesized by synthesizing intermediates of the general formula (1), in which functional groups such as carboxylic acid and phenol functional groups are introduced into R₁ or R₂, and introducing the functional groups from these intermediates into these derivatives by an appropriate reaction.

If the functional groups introduced at the ends are previously introduced into a carboxylic acid derivative (7), a bromide derivative (9), a styrene derivative (11), an aryl halide derivative (21), an aldehyde derivative (24), a substituted phenylboronic acid (34) and the like, then these functional groups are protected and deprotected by an appropriate method as necessary in a process of synthesis by the same method as the method of manufacturing the general formula (1).

If the functional groups introduced at the ends are introduced into these derivatives by synthesizing intermediates of the general formula (1), in which a functional group such as carboxylic acid and phenol functional groups is introduced into R₁ or R₂, and introducing the functional groups from these intermediates by an appropriate reaction, then amidation, Mitsunobu reaction or the like is preferred as such an appropriate reaction. The functional groups are protected and deprotected by an appropriate method as necessary. For example, to introduce alkenyl or azido into R₁, amidation reaction is performed between a compound of the general formula (1), in which carboxylic acid is introduced into R₁, and an alkylamine with alkenyl or azido bonded thereto. To introduce alkenyl or alkynyl into R₂, Mitsunobu reaction is performed between a compound of the general formula (1), in which phenol is introduced into R₂, and an alkylamine with alkenyl, alkynyl or a protected amine bonded thereto. Raw materials for synthesizing the general formula (2) can be synthesized by combining these reactions of introducing functional groups into R₁ or R₂.

The compound (7), compound (9), compound (11), compound (21), compound (24) or compound (34) used in the above reactions can be synthesized from known compounds using appropriate reagents and reactions. For example, an amino group, if present in R₁ or R₂, may be alkylated, acylated, carbamated, converted to ureas or sulfonamidated from known compounds. Carboxylic acids or esters, if present, may be amidated under general conditions. Sulfonyl chlorides, if present, may be condensed with amines and sulfonamidated. Alcohols, if present, may be etherified or carbamated. Aryl halides, if present, may be coupled with arylboric acids or aryl boronates under general Suzuki conditions. Olefins, if present, may be reduced or converted to diols. Thioether groups, if present, may be oxidized to sulfoxides or sulfones. If ketones or carbonyl groups are present, the carbon chain may be extended by Wittig reaction, Horner-Wadsworth-Emmons reaction, aldol reaction or the like. In the introduction of fluorine atoms, reagents containing fluorine atoms may be introduced by these reactions, or aldehydes, ketones or carboxylic acids may be reacted with diethylaminosulfur trifluoride, for example.

The techniques for introducing these groups can be performed with reference to March, Advanced Organic Chemistry, 5^(th) Edition, John Wiley and Sons, New York; J. Med. Chem., 2005, 48, 6066-6083; Organic Syntheses (1951), 31, 8-11; Bioorg. Med. Chem. Lett., 2003, 13, 837-840; Chem. Rev. 2002, 102, 1359; J. Organomet. Chem. 1999, 576, 147; Chem. Rev. 1995, 95, 2457, for example. These groups may be protected with protecting groups under general conditions, if necessary. This can be performed with reference to Protective Groups in Organic Synthesis, Wiley-Interscience, for example.

For example, amines may be alkylated, acylated, carbamated, converted to ureas, sulfonamidated or sulfamidated under general conditions. Carboxylic acid and ester moieties may be converted to amides under general conditions. Amido groups may be converted to thioamido groups. Olefins may be reduced or converted to diols. Thioether groups, if present, may be oxidized to sulfoxides or sulfones.

This can be performed with reference to Protective Groups in Organic Synthesis, Wiley-Interscience, for example. Aryl halides may be coupled with arylboric acids or aryl boronates under general Suzuki conditions. This can be performed with reference to Chem. Rev. 2002, 102, 1359; J. Organomet.

A saturated aqueous sodium bicarbonate solution was added, and the organic layer and the aqueous layer were separated. The aqueous layer was then further extracted with dichloromethane. The organic layers were combined, dried over anhydrous sodium sulfate and then concentrated under reduced pressure. The resulting solid was washed with n-hexane and then collected by filtration and dried under reduced pressure to give 1-(3-chloro-benzenesulfonyl)-piperidin-4-one as a white solid (10.5 g, 97%).

Thereafter, sodium cyanide (724 mg, 14.77 mmol) was added, and the mixture was further stirred for 17 hours and then quenched with a saturated aqueous sodium carbonate solution. The organic layer and the aqueous layer were separated, and the aqueous layer was then further extracted with ethyl acetate:n-hexane (4:1). The organic layers were combined, washed with water (×4), and then dried over anhydrous sodium sulfate and concentrated under reduced pressure.

A solution of cyclohexanecarbonyl chloride (118 μL, 0.880 mmol) in chloroform (0.25 mL) was added to a mixed solution of 4-amino-1-(3-chloro-benzenesulfonyl)-piperidine-4-carbonitrile (120 mg, 0.400 mmol) in chloroform (1.25 mL) and a saturated aqueous sodium carbonate solution (1.25 mL), and the mixture was vigorously stirred at room temperature for 16 hours. Cyclohexanecarbonyl chloride (51 μL) was further added and the mixture was stirred for 2.5 hours. The organic layer and the aqueous layer were then separated, and the aqueous layer was further extracted with chloroform.

A 6 M aqueous sodium hydroxide solution (0.74 mL) and a 30% aqueous hydrogen peroxide solution (0.25 mL) were added to a solution of cyclohexanecarboxylic[1-(3-chloro-benzenesulfonyl)-4-cyano-piperidin-4-yl]-amide (100 mg, 0.244 mmol) in ethanol (1.60 mL), and the mixture was heated under reflux for 4.5 hours. The reaction mixture was cooled to room temperature and water was then added, followed by concentration under reduced pressure. The residue was neutralized with a saturated aqueous ammonium chloride solution, followed by extraction with dichloromethane. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (dichloromethane:methanol=90:10) to give 8-(3-chloro-benzenesulfonyl)-2-cyclohexyl-1,3,8-triaza-spiro[4.5]dec-1-en-4-one as a white solid (52 mg, 52%).

HKRK-B7 or LLC-PK1 cells were seeded in a 96-well plate at 1×10⁵ cells/well and incubated overnight. On the following day, 50 μl of cAMP assay buffer (DMEM, 2 mM IBMX, 0.2 mg/ml bovine serum albumin, 35 mM Hepes-NaOH, pH 7.4) containing human PTH(1-34) or Compound was added and the plate was placed in a 37° C. incubator. The cells were incubated for 20 minutes. After removing the medium, the cells were washed with 100 μl of cAMP assay buffer once. The plate was placed on dry ice powder to freeze the cells and then removed from the dry ice. The cells were lysed with 40 μl of 50 mM HCl and frozen again on dry ice. The amount of intracellular cAMP produced was measured using a commercially available cAMP EIA kit (Biotrack cAMP EIA system, GE health care).

The compounds of the present invention demonstrated a significant cAMP response in HKRK-B7 cells. Table 195 shows percentage values obtained by dividing the amount of cAMP produced by the compound of the present invention in HKRK-B7 cells at 1×10⁻³ M (*at 3×10⁻⁴ M for Compound 15) by the amount of cAMP produced by hPTH(1-34) as a positive control at 100 nM. The degree of cAMP response in LLC-PK1 cells was lower than the degree in HKRK-B7 cells.
